According to most legitimate online information available, the Seiko 4361 is the same as the 436 movement that made its debut in 1960 and lasted until 1969. This movement was predominantly used in the Seiko Sportsman series. It is a mechanical watch that manually must be wound. Power reserve is 41 hours when the watch is fully wound.

The objective was to create a sporty watch with certain dress watch features with a bigger dial. This watch is the predecessor of the Seiko Sportsmatic range.

Unsurprisingly, mechanical hand wound watches are making a subtle but certain comeback in recent times because many from the younger generation have gone "retro" and vintage watches especially hand-wound units have become a must-have. This has not gone unnoticed by many watch companies so much so that Seiko, Orient etc. have launched "re-editions" of famous vintage models however, current movement models are used instead.

For Seiko Collectors and Vintage fans, this is a pre-SUWA (logo) Seiko Seikosha in near mint condition, and it is a Collectible due to its age and most importantly, its movement and AD status.

This extremely rare Seiko Sportsman is a sight to behold! It's original egg white dial is in pristine condition after a good clean-up, so too the 14K solid-gold baton indices, hands, and gold-filled case.

The timeless cylindrical shaped gold-filled case was buffed as best as possible; however, there are some hairline scratches present. The glass is original and was given a good rub-down but nonetheless, hairline scratches are still present but unnoticeable.

The crown is located at the traditional 3H position and is easily accessible.

The movement was carefully stripped, cleaned, oiled, re-assembled and calibrated in September 2022. It should be able to operate unhindered for the next 5 to 10 years thereby providing the buyer peace of mind.

Equipped with the well revered 4361 movement, it has 17 Jewels that operate at 18,000 beats per hour (BPH) giving it excellent accuracy and longevity. The time-grapher shows excellent readings i.e. rate of "0" seconds every 24 hours and amplitude of 266! Such readings are exceptional even by brand new automatic watch standards whereby the accepted tolerance is -20- to +40 seconds a day! This is a testament to the quality, excellent power reserve and longevity for such a vintage timepiece, the meticulous care provided over the years, and of course the painstaking calibration conducted.

The case width and height are approximately 38mm (without crown) and 42mm respectively. The lug width is 19mm and the leather strap can accommodate wrists up to 21cm; hence, this watch is suitable for men and the modern women.

A beautifully crafted hand-stitched high quality genuine leather cherry red + earthy brown strap with brown stitching and gold buckle is provided to enhance the colour of the case and dial. 

To the best of our knowledge and expertise when overhauling the timepiece, the watch is 100% original Seiko components from this particular watch. No parts were replaced with aftermarket parts or modified.

Due to its age, this timepiece has not been water-resistant tested.

The pictures provided show the watch's case in pristine condition (no dents, dings and major scratches), and the movement within squeaky clean and well maintained. It has also been demagnetised to improve parts reliability, minimise wear & tear, and improve accuracy. The only drawback is the lack of documentation and original box. An aftermarket box or purposeful carrying case will be provided instead.

Seldom can one find a vintage watch that offers this and more. Yes, there are many other same / similar models in the market, BUT none are as well-kept and maintained as what you see here, and with an attractive price to boot. So, it is a no-brainer that this one-of-a-kind watch will make an extremely beautiful birthday present for that special someone born in August 1963! Another no-brainer is the fact that the value of this watch will appreciate over time.

Bear in mind that this watch has seen many of the previous owners’ ups and downs in life, and should be cherished and well taken care of for the next generation to savour such engineering beauty.

Do also bear in mind that it will cost between S$ 120.00 to S$ 150.00 for a proper servicing, an estimated S$ 80.00 to calibrate (depending on watch condition), and S$ 100.00 to clean and polish including tightening of bracelet links - these costs do not apply when purchasing this timepiece. So, if anyone was to sell such a timepiece at a low price yet claim that it has been serviced, one has to ask what kind of servicing was conducted, if any.

This is a truly magnificent February 1968 Gold-Filled Seiko Seikosha DAINI in near-mint condition with a beautifully preserved vintage dial, immaculate indices, hands, movement and case; so, be unique and use something that is almost impossible to source.

This is a must-have for the Seiko die-hard fan, or any vintage watch fan for that matter!
